            Bug ID: 103868
           Summary: VK_PRESENT_MODE_MAILBOX_KHR blacks out the whole
                    screen intermittently when using X11 compositing
                    window managers
           Product: Mesa
           Version: 17.2
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: minor
          Priority: medium
         Component: Drivers/Vulkan/radeon
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: sbrown124 at gmail.com

If you can reproduce this on your computer, you should be able to with the
LunarG Vulkan SDK cube program. Run it like so:

$ ./cube --present_mode 1

You need to run a compositing window manager and alt-tab out or go to a
different window to reproduce this, as far as I can tell. It doesn't happen
when running under XMonad or Kwin with composition disabled with Alt+Shift+F12.
You should see the screen blank out to black.

OS: Arch Linux x86_64
GPU: Radeon RX 460 2GB
Display connected by DVI-D
Window managers with the issue: Kwin, Mutter

I haven't tested whether the issue shows up with Wayland yet. I don't expect it
to, but if it does, I'll leave a comment.
